Rated 4.8 out of 5 by 301 reviewers.
Rated 5 out of 5 by High performance, quiet, efficient furnace The SLP98V is a highly efficient, quiet, high performance furnace. With a 98% efficiency rating for propane or natural gas is phenomenal. Converted from Oil heat to propane with a 18% increased efficiency rating not even factoring in the efficiency of the modulating system. Instaled a combination unit with heat pump and A/C for all season home comfort management. The dynamic thermostat monitor has multiple seasonal programs and times for personalized efficiency by home life. The thermostat even includes outside temperature, humidity and temperature settings. Highly recommend the combination units. November 16, 2012
Rated 1 out of 5 Needs repairs every season Installed my furnace feb 2010, I was impressed by how efficient this product was and quiet. Had the pressure switch replaced numerous times, found out this part was recalled. Now I had a burnt out processer on control panel today. I can't see how this happened. I have a whole house ground fault that wasn't triggered at all. My unit was never running during any storm this summer. I have tons of electronic items in my house, so why did it burn out the processer on the furnace only? Called a few places with no definite answers. That frustrates me. September 16, 2014
Rated 5 out of 5 High quality, high efficiency and quiet. We wanted a high quality, high-efficiency and quiet furnace that would provide us years of service. Though we haven't experienced winter since installation this model promises to more than meet our expectations. September 16, 2014
Rated 1 out of 5 by This furnace is not dependable Last night we again slept without heat. It's the 5th time this year the furnace went out!! Even though it's still under warranty we're ready to find a more dependable furnace!! September 12, 2014
Rated 4 out of 5 by works well Furnace just installed a few weeks ago and haven't yet had the opportunity to fully see what it can do in the winter. so far furnace has been near silent for the circulating fan and has kept the temperature in the house exactly to the temperature set with little to no variantion.

Rated 5 out of 5 by New SLP98V Furnace Based on what I have read, this furnace has it all and a credible track record on consumer review websites as well. Afterall, it is a Lennox and one of the most reputable brand names in the business. While it has not been cold enought to really test the new furnace yet, if it has the same quality we saw in the AC we purchases, we're expecting a completely modular system with the ability to maintain temperature easily and energy savings.

Rated 5 out of 5 by My home has never been so comfortable! I can't believe the difference in the comfort of our home. I live in a split level house and have always had trouble trying to keep the different levels at an even temperature. This system makes it so the entire house is about the same temperature throughout. The Wi-Fi thermostat makes it easy to program and reduces the cost of climate control. I can set the system to reduce output while I am away for an extended time. Before I return home I can reset my preferred programming from a remote location. By the time I arrive home the house is back to comfortable temperatures. This saves us a lot of money. Finally, I need to mention how quiet the system is. The furnace room is very close to my bedroom. The noise has been reduced by at least 75% from the old furnace. The air conditioner is just unbelievably quiet. I could not be happier with my choice of this system! September 7, 2014
Rated 5 out of 5 by Compact and Clean Design We recently had a new Lennox 98% energy efficient furnace installed and we especially like the compact size and clean design look of this new furnace. We also really like the LED thermostat. It is easy to read, easy to operate, and has nice bright display. Excellent overall design. September 4, 2014

*This chart depicts potential energy savings you can expect from the SLP98V furnace, versus older furnaces with lower efficiency ratings. Criteria used in this example are 2,000 full-load heating hours, with a 60,000 Btuh heating design load and $1.368 ccf for gas. Your actual savings may vary, depending on the weather patterns in your local area, local fuel rates and your individual lifestyle.
**iComfort Wi-Fi® Touchscreen thermostat must be installed with an iComfort-enabled indoor unit for maximum performance.
